Filter by:Background The exacerbation of respiratory failure that occurs after endotracheal intubation often occurs in patients who have received mechanical ventilation therapy, and when it occurs, it emerges as an important issue to consider reintubation of endotracheal intubation. High-flow nasal cannula (HFNC) through nasal cannula is known to produce positive airway pressure and deliver a certain amount of oxygen, and recently reported clinical studies have demonstrated the effect of lowering the risk of reintubation after endotracheal intubation, which is recommended for use in recent clinical practice guidelines. However, in patients at high risk of intubation failure, the combination of high-flow oxygen therapy and non-invasive positive-pressure ventilation therapy rather than the application of high-flow oxygen therapy alone through nasal cannula is helpful in reducing the rate of reintubation of endotracheal intubation. However, an alternative to non-invasive positive-pressure ventilation therapy is needed as there is a possibility of complications such as aspiration pneumonia, maladaptation of the application device (mask), and discomfort, making it difficult to apply it in the field. Recently, it has been reported that high flow oxygen therapy through an asymmetric nasal cannula forms sufficient positive pressure in terms of respiratory dynamics, which makes the patient feel comfortable and reduces work of breath. However, no clinical studies have yet compared physiological effects using this method in patients at high risk of extubation failure. Goal The investigators would like to compare the physiological effects of high flow oxygen therapy through 'asymmetric nasal cannula' with high flow oxygen therapy through 'standard nasal cannula' in patients identified as high-risk groups for valvular failure. Hypothesis 'Asymmetric nasal cannula' reduces work of breath compared to 'standard nasal cannula' in high-risk patients with valvular failure.
During cardiopulmonary bypass (CPB), oxygenation of the patient on the pump can be left completely under pump control, or the lungs can be ventilated with low tidal volume to reduce atelectasis. In recent years, the concept of mechanical power has been used to determine the extent of ventilator-related lung damage. This concept of mechanical power, by which the energy transferred by the ventilator to the lungs can be calculated, will be measured at certain intervals in CPB surgery patients on the pump and compared between the two groups. The investigators aimed to investigate the effect of two different ventilation methods on mechanical power and its relationship with postoperative pulmonary complications.
Impaired respiratory function may occur after brain injury, and will progress to restricted respiratory dysfunction without early intervention. At present, there is a lack of effective treatment options for respiratory dysfunction. Repetitive Transcranial Magnetic Stimulation(rTMS) is a non-invasive, painless and non-invasive neuroregulatory technique. In healthy people, rTMS applied to the respiratory motor cortex induces a contralateral respiratory muscle response. However, whether rTMS can improve respiratory function in patients with brain injury remains unclear. gut microbiota can affect muscle function and mass, and animal experiments have shown that probiotics can increase skeletal muscle mass and grip strength in mice. On the other hand, studies have found that rTMS can improve the nutritional status of patients with vegetative state by regulating the structure of gut microbiota. However, it remains unclear whether rTMS can improve respiratory muscle function in patients with brain injury by regulating gut microbiota. Therefore, the investigators intend to apply rTMS to the respiratory motor cortex to observe whether rTMS can improve respiratory function and reduce the incidence of pneumonia in patients with brain injury, and to observe the role of gut microbiota in this process.
Even though nutrition is a fundamental component of Intensive care unit (ICU) therapy, critically ill patients are frequently malnourished, a factor well known for its strong association with a higher risk of complications, prolonged ICU/hospital length of stay, and greater ICU readmission and mortality rates. Noninvasive ventilation (NIV) use has increased considerably over the past twenty years, making this supportive technique a keystone of acute respiratory failure (ARF) treatment. In this setting, respiratory support is provided through an interface, usually a mask or a helmet, that frequently represents an important obstacle to nutrition delivery, making oral intake impossible and posing the necessity to start enteral (EN) or parenteral nutrition (PN). Moreover, while critical care guidelines regarding nutritional management of patients receiving mechanical ventilation (MV) are well established, data and recommendations about the appropriate nutritional support to patients in NIV are still very limited. Due to this limited data, we want to describe characteristics and nutritional management of patients undergoing NIV in ICU, and to evaluate the difference between the mean caloric and protein intake of these patients and the recommended caloric and protein target for critically ill patients. Secondarily, we want to evaluate the difference of the caloric and protein intake among groups of patients undergoing different nutritional modality and to assess potential associations of the nutritional characteristics with patient outcomes.
Hypothesis Treatment with HFNC and OptiflowTM+Duet can significantly reduce PaCO2 and normalize pH in patients with COPD exacerbation and acute hypercapnic failure, compared to HFNC with OptiflowTM. Treatment with High flow and OptiflowTM+Duet in patients with COPD exacerbation and acute hypercapnic failure is well tolerated. Aims To investigate the effect of HFNC in combination with either OptiflowTM or OptiflowTM+Duet nasal cannula on PaCO2 levels and pH in patients with COPD exacerbation and acute hypercapnic failure and compare the results of treatment with the two different nasal cannulas. To describe adherence to treatment with high flow and either OptiflowTM or OptiflowTM+Duet nasal cannula. Methods Study design The study will be carried out as a prospective, multicenter, randomized controlled trial. - Patients COPD and acute hypercapnic who do not tolerate NIV-treatment will be treated with HFNC for respiratory support. Patients will be randomized to either OptiflowTM /OptiflowTM+Duet nasal cannulas ("Fisher & Paykel Healthcare", Auckland, New Zealand) - HFNC treatment with allocated nasal cannula, flow 40-60 (prescribed by the responsible clinician) will be initiated, titration of FiO2 till target SO2 is reached (as prescribed by the responsible clinician or by default 88-92%). Maximal flow and target saturation should be reached within 1.5 hours of initiation. - Arterial puncture (registering pH, PaO2, PaCO2, HCO3, SaO2 and Base Excess) will be drawn at baseline and repeated after two hours (±30 minutes and after flow and FiO2 have been stable for 30 minutes) and at termination of the HFNC. - Patients will remain in study till it is decided by the treating physician to terminate HFNC-treatment. Patients who are candidates for invasive ventilations will be excluded from the study if the arterial blood gasses further deteriorate after initiation of HFNC.
Sedation remains a ubiquitous and crucial component of intensive care treatments in critically ill mechanically ventilated patients. Sedation relieves anxiety, reduces distress, and promotes tolerance of endotracheal intubation and associated life-sustaining interventions such as mechanical ventilation, cardiovascular assistance, and renal support. Thus, choosing the optimal sedative agent is vital to patient comfort, safety, and survival. Despite more than 20 years of intensive care sedation research, there is still no consensus on what constitutes best sedation practice. The Society of Critical Care Medicine, the premier critical care organisation in North America, published the 2018 Clinical Practice Guidelines on the management of Pain, Agitation/Sedation, Delirium, Immobility and Sleep (PADIS) disruption (chaired by our primary applicant W.A.) and issued weak recommendations to provide analgesia before sedation, to target light sedation whenever clinically feasible, and to use either dexmedetomidine or propofol over midazolam for the sedation of mechanically ventilated critically ill patients. Similarly, the American Thoracic Society produced a set of Clinical Practice Guidelines to promote liberation and weaning from mechanical ventilation in critically ill patients, with weak recommendations for the use of non-benzodiazepines as primary sedatives and to target light sedation when clinically possible. A weak recommendation was issued in an Intensive Care Medicine Rapid Practice Guideline published in 2022 to use dexmedetomidine over propofol for sedation of critically ill adults, if the desired outcome is a reduction in delirium. These guidelines, however, do not consider age-dependent pharmacokinetics and pharmacodynamics, illness severity, timing of sedative administration, operative vs medical reason for admission, or the changing dynamics of sedation practice at different phases of critical illness. The lack of high-level evidence to inform sedation practice in the critically ill has led to approaches that are mainly opinion-based and lack the support of evidence from large multicentre, international randomised clinical trials.
This is a registry-based, randomized, controlled clinical trial of the effect of added high-flow oxygen therapy (using the device Lumis HFT) during one year in people with long-term oxygen therapy (LTOT) for chronic obstructive pulmonary disease (COPD) or interstitial lung disease (ILD).
The goal of this feasibility study is to learn about the ability to use a different form of oxygen therapy (known as high flow oxygen therapy) in patients who have a spinal cord injury in the upper back or neck. The main questions it aims to answer are: 1. Is it possible to recruit patients to the study 2. It is possible to follow the protocol in its current format 3. What is the impact on those receiving the intervention. Participants will be randomised to receive either standard care or high flow oxygen therapy for 10 days following inclusion.
The goal of this worldwide observational study is to investigate ventilation practice in critically ill pediatric patients. The main questions it aims to answer are: 1. What is the global current practice of ventilatory support in critically ill pediatric patients? 2. Which potentially modifiable factors related to ventilation are associated with outcome? Participating pediatric intensive care units will gather detailed information about ventilation practice and outcome, such as duration of ventilatory support, length of ICU stay and ICU mortality.
Non-invasive ventilation is a mechanical ventilation who provides ventilatory support through a facemask, and without the need for tracheal intubation. In the emergency department, non-invasive ventilation is commonly used for the management of acute respiratory failure related with acute exacerbation of chronic obstructive pulmonary disease or with cardiogenic pulmonary oedema. Non-invasive ventilation is associated with an improvement in the outcomes, such as a decreasing in the intubation rate and in the mortality rate. Non-invasive ventilation failure is defined by a requirement to tracheal intubation in a patient managed by non-invasive ventilation. In the intensive care unit, non-invasive ventilation failure is reported from 15 to 50% of patients according to the ARF aetiologies. Due to delayed intubation, non-invasive ventilation failure is associated with poor outcomes and an increasing in the mortality rate. Due to the emergency department's patients (older and/or not to be intubate patients) the actual definition of non-invasive ventilation failure could not be applied as non-invasive ventilation may have been stopped not because it was unsuccessful but because it was unsuccessful in a patient with a do not intubate decision. Consequently, the prevalence of the absence of non-invasive ventilation success in the emergency department is unclear, and its predictive factor are unknown. The aim is to measure the prevalence of the absence of non-invasive ventilation success in the emergency department. The secondary objective is to measure the association between an absence of non-invasive ventilation success and outcomes and to identify risk factor of an absence of non-invasive ventilation success in the emergency department. It's a prospective observationnal multicenter study in department of Initiative Recherche Urgences Study Groups from January 2024, 15th to January 2024, 20th. The Initiative Recherche Urgences is a research network set up on the initiative of the Société Française de Médecine d'Urgence, with the aim of promoting and coordinating multicentre research projects in the field of emergency medicine, during short inclusion periods. The primary outcome is the proportion of patients who do not have an early success of non-invasive ventilation. The investigators measure the absence of success instead of failure because failure is defined by intubation and most of patients managed with non-invasive ventilation in an emergency department will not be intubated because of their age. The absence of success is defined by at least one of the following criteria measured at 1-hour: death, cardiorespiratory arrest, tracheal intubation, respiratory rate over 30 breaths/min, neurological impairment defined by a Glasgow coma scale < 14, signs of increased work of breathing, haemodynamic failure (defined by mean arterial pressure < 65 mmHg despite volumetric expansion and/or catecholamines), early stop of non-invasive ventilation due to intolerance. The investigators choose to measure at one hour because non-invasive ventilation is provided from one to two hours in the emergency department.
